PAPER RECEPTACLE.

Specification of Letters Patent.

Patented June 12, 191?.

Application filed April 24, 1913. Serial No. 763,241.

To all whom it may concern:

Be it known that I, HENRY A. HOUSE, a citizen of the United States, residing at Bridgeport, in the county of Fairfield and State of Connecticut, have invented certain now and useful Improvements in Paper Receptacles; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appentains to make and use the same.

My invention relates to paper receptacles and covers for same. It consists chiefly in reinforcing the rim of receptacles by compressing the paper under heat and moisture, and also to form in like manner, a reinforced edge on the cover. It further consists in giving a parabolic receptacle. v

Referring to the drawings, wherein the same figures and letters of reference indicate like parts throughout the several views;

Figure 1 represents a partially formed plaited receptacle;

Fig. 2 is a broken view partly in section of a receptacle properly shaped before the rim or lip is compressed;

Fig. 3 is a broken view partly in section showing the rim compressed and reinforced; and

Fig. 4 is a broken view partly in section of the receptacle and its cover showing the rims of both reinforced.

The plaited construction 1, Fig. 1 is formed by means of a proper shaped punch and die (not shown) into the form shown in Fig. 2. The contour of the body 2 will be of parabolic form, and the olfset rim 3, straight. The rim shown in this view, is made long enough to furnish the proper amount of stock for compression, while in the die, this elongated rim is upset or compressed under heat, moisture and pressure to form the heavy reinforced rim shown in Fig. 3. In like manner, but with different tools (not shown) the cover 4 is provided with the reinforced edge 5. The annular depression or groove 6 in the cover, serves in conjunction with the rim 7 to securely locate the cover on to the mouth ofthe receptacle. The comparatively thin body portion of the receptacle is sufficiently strengthened by said cover and rim. 1

form to the body of the" a rim for the lip of the its parabolic shape to resist all internal and external pressure, to which a receptacle 0 this kind would be subjected to. But, if the offset rim3 was of the same thickness as the body, it would be, impossible for it to withstand the pressure brought to bear against it by the cover to make a tight joint between therefore reinforce and strengthen, as before mentioned, the rim by upsetting or compressing the paper stock, under heat, moisture and pressure into a compact form, so that it will remain rigid and unyielding when the cover is forced on. Having thus described my invention, what I claim is:

1. A paper receptacle pressed from a single sheet of seamless paper, having its side walls bent upward from the bottom substantially perpendicular to the bottom, and plaited to form sections of a plurality of thicknesses of paper, these sections of a plurality of thicknesses of paper gradually tapering from the top toward the bottom with the plurality of thicknesses of paper pressed together, and a rim for the lip of the cup formed substantially by the widest part of the plaited sections of a plurality of thicknesses, compressed under heat and moisture into a compact form, for reinforcing and strengthening the top of the receptacle.

2. A paper receptacle pressed from a sinle sheet of seamless paper, having its side walls bent upward from the bottom substantially perpendicular to the bottom, and plaited to form sections of a plurality of thicknesses of paper, these sections of a plurality of thicknesses of paper gradually tapering from the top toward the bottom and cup formed substantially by the widest part of the plaited sections of a plurality of thicknesses, compressed under heat and moisture into a compact form, for reinforcing and strengthening the top of the receptacle.

3. A paper receptacle pressed from a sinle sheet of seamless paper,-having its side walls bent upward from the bottom substantially perpendicular -to the bottom, and

plaited to form sections of a plurality of of paper, these sections of a graduthicknesses plurality of thicknesses of paper ally tapering from the top toward the bottom, a rim for the lip of the cup formed substantially by the widest part of the plaitcd sections of a plurality of thicknesses, compressed under heat and moisture into a compact form, for reinforcing and strengthening the top of the receptacle and a cover having a rim compressed under heat and moisture into a compact form snugly fittin the compressed rim of the receptacle.

In testimony whereof I aflix mv si 'nature in presence of two witnesses.
